To all whom it may concern:

7 Be it known that I, HOWARD M. BARBER, a citizen of the United States,and resident -of Stonington, in the county of New London and State ofConnecticut, have invented a newand useful Improvement in SheetCollecting, Associating, and Folding Machines, of which the following isa specification.

The object of this invention is to provide novel means for associatingextra sheets fed from different sources of sheet supply, such, forinstance, as cover and insert sheets, with a collected group of sheetsfed from another source of supply, means preferably being employed forstitching the so associated sheets together for folding the same.

My invention more particularly includes a rotary sheet associatingcarrier, a rotary sheet collecting carrier arranged totransfer groups ofsheets to the associating carrier, and rotary sheet carriers eacharranged to transfer a sheet from a source of extra sheet supply to theassociating carrier whereby the collected group of sheets and the sheetsfrom the difi'erent sources of sheet supply are combined on theassociating carrier.

vA practical embodiment of mya-invention is represented in theaccompanyingdrawings, in which Figure 1 represents a detaillongitudinalvertical central section through so much of a sheet collecting,associating and folding machine, as includes my invention,

Fig. 2 represents a similar section taken just inside the near sideframe,

Fig. 3 represents a similar section taken just inside the far sideframe, and I Fig. 1 is a similar section taken just outside the far sideframe, showing the geared connection between the several parts.

1 designates a source of extra sheet-supply, such, for instance, as aninsert sheet supply. 2 designates a difierent sourceiof extra sheetsupply, such, for instance, as a cover sheet supply. These sources 1 and2 are herein shown as feed tables, the table 1 being provided with amovable sheet stop 3 and the table 2 with a movablesheet stop 4:.

Rotary cutters 5, 6, mounted on suitable shafts 7, 8, are arranged tocuta single web or a plurality of superimposed webs which pass betweenthe rolls 9, 10, into sheets, which sheets are passed downwardly betweenthe guides 11, 12, to a three way collecting rotary carrier 13, mountedone-shaft 14, which carrier, in-the present instance, is shown as beingprovided with three sets of grippers 15. Tucking disks. 16, mounted onthe shaft 17, serve to insure the engagement of the advance edges of thesheets by the grippers 15. v

The rotary sheet associating carrier 18, mounted on the shaft 19, isherein shown as havlng three sets of grippers 20. rotary sheet transfercarrier 21 mounted ,on the o5 shaft 22 is provided with a; set lofigrippers 23 arrangedto feed an extrasheet as, for in,- stance, an insertsheet, from 'the source of extra sheet supply v1 to the grippers 20 onthe rotary sheet associating carrier 18. A rotary sheet transfercylinder 24, mounted on the shaft 25, is {provided with a set ofgrlppers 26 arranged to feed a sheet, such, for instance, as a coversheet, from the source of extra sheet supply 2 to the grippers 20 on thesheet associating car-rier18. I A stitcher table 27 is arranged toreceive the associated sheets, on which table the sheets are stitchedtransversely of their travel by the coacting parts 28, 29, of two ormore stitchers. A movable stop30is located at the outer endof thestitcher-table 27 in position to engage the advance edges of theassociated sheets and hold them momenta rily in position for thestitching operation. Coacting rotary carriers 31, 32, mounted on theirrespective shafts 33, 34,,are',provided, the carrier 31 havinga set ofgrippers 35 arran edto take the stitched-assoe ciated sheets from thestitcher table 27 and also having a folding blade3 6 arranged to coactwith the folding jaws 37 on the-rotary carrier 32 for imparting atransverse fold to the associated sheets along their trans verselystitched line. i Endless carriers 38, 39, serve to carry the associatedsheets .onto and off from the stitcher table 27 and endless carriers LO,41, are arranged to carry the product from the rotary carrier 32 toa-suitable delivery 42, The train of gears, designated by 14 to 7-1inclusive, is operative to drive the parts at the proper relativespeeds. I I i A switch 72 is located at thetentrance end of the stitchertable 27, which-switch TSQPfi erated from a cam 73 on the shaft 33 ofthe rotary carrier 31 through the connection 74:

A fixedcam 75 opens the grippers :15 successively at their sheet;receiving point. Movable cams =7 6, -7 7, open the grippers '20 and 15,every two-thirds of a revolution of the rotary carriers 18 and 13 totransfer a group of sheets from the carrier 13 to the carrier 18. Thesemovable cams 76, 77, are operated from the rotary cam 78, on the shaft79, through the connection 80. A movable cam 81 operated from the rotarycam 82 on the shaft 22 through the connection 83, is arranged to openalternate grippers 20 on the associating carrier 18 to receive a sheet,as, for instance, an insert sheet, fed from the source of extra sheetsupply 1 by the rotary carrier 21.

A movable cam 84 operated from the rotary cam 85 on the shaft 25 throughthe connection 86 is arranged to open alternate grippers 20 to receivean extra sheet, as, for instance, a cover sheet fed from the source 2 ofextra sheet supply, by the rotary carrier 24.

A fixed cam 87 is arranged in position to open the grippers 23 totransfer the extra sheet therefrom to alternate grippers 20 on theassociating carrier 18 every vrevolution of the carrier 21. A fixed cam88 is arranged in position to open the grippers 26 to transfer a sheetto alternate grippers 20 on the associating carrier 18 every revolutionof the rotary carrier 24.

A movable cam 89 operated by the rotary cam 90 on the shaft 22 throughthe connection 91, is arranged to open alternate grippers 20 on theassociating carrier 18 to re lease the associate group of sheets andextra sheets from the difierent sources of supply to permit the soassociated sheets to be fed onto the stitcher table 27.

The grippers 23 are tumbler operated for taking the sheets from thesource of sheet supply 1, the tumbler 92 being controlled by the pins93, 94. The grippers 26 are also tumbler operated to take the sheetsfrom the different source of sheet supply 2, their tumbler 95 beingcontrolledby the pins 96, 97.

The movable sheet stop 3 is controlled by the cam 98'Wl110l1 is arrangedto engage the stop roller 99.

The movable sheet stop 4 is controlled by the cam 100 which is arrangedto engage'the sheet stop roller 101.

The sheet stop 30 is controlled by the cam 102 which is arranged toengagethe sheet stop roller 103.

The set of grippers 35 on the rotary car-' rier 31 is tumbler operatedto take the sheets from the stitcher table 27, the tumbler 104 beingcontrolled by pins 105, 106.

v The coacting folding mechanism on the rotary carriers 31, 32, is ofthe well known floating blade and jaw type, the operation of the blade36 being controlled by the cam 107 and the operation of the jaws 37being controlled by the cams 108, 109, 110.

-A fixed cam 111 is arranged to open the t5 grippers-35 at the time offolding.

Positively driven rollers 112, 113, bear against the surface of therotary carrier 18 and positively driven rollers 114, 115, bear againstthe surfaces of the rotary carriers 21, 24, for holding the sheets inregister on their respective surfaces when their grippers are opened.

In operation the rolls 9, 10, are arranged to feed one or more Webs tothe rotary cutters, 5, 6, the collected sheets are severed from the webor webs, and fed through the guides 11, 12, to the collecting carrier13. The carrier is herein shown as being an ranged to collect two sheetsor groups of superimposed sheets and transfer the same to theassociating carrier 18 on top of an extra sheet, as, for instance, aninsert sheet fed from the source of sheet supply 1 to the associatingcarrier 18 by the rotary carrier 21.

The rotary carrier 24 is arranged to transfer a sheet, as, for instance,a cover sheet, from the source of extra sheet supply 2 to theassociating carrier 18 on top of the group of sheets. The so associatedsheets are then fed onto the stitcher table 27 the switch 7 2 beingdepressed to insure the passage of the so associated sheets onto thetable. These associated sheets are fed against the stop 30 and Whileheld momen- 9 tarily thereby, the sheets are stitched transversely oftheir travel. The sheets are then released by the stop 30 and theiradvance edges are taken by the grippers 35 of the rotary carrier 31. Thesheets are then folded off transversely of their travel along theirstitched line onto the rotary carrier 32 and from thence they are fed byendless carriers 40, 4-1, to the delivery 4-2, 43.

From the above description it will be seen that the sheets from thedifferent sources of extra sheet supply are fed'to the same side of theassociating carrier at dilferent points thereon and that the group ofsheets 5 are fed to the associating carrier at still another point, theassociating carrier'being arranged to first take an extra sheet as, forinstance, an insert sheet, then take a group of sheets on top of theinsert sheet, and finally take another extra sheet, as, for instance, acover sheet, on top of the groupof sheets and feed the same to thestitcher table. This makes a very simple and efiee tive arrangement.

It is obvious that the rotary carrier 13 can collect a group of singlesheets or a group of superimposed sheets and it is also obvious that theextra carriers 21 and 24 may feed one or more sheets from theirrespective sources of extra sheet supply, Without departing from thespirit and scope of my invention.

It is evident that changes may be resorted to in the form, constructionand arrangement of the several parts without departing 13c from thespirit and scope of my invention; hence I do not WlSh to limit myselfstrictly to the structure herein shown and described,

to the associating carrier, and means for stitching and folding the soassociated sheets together and delivering the same.
